Maintenance

Cleaning the Projector

Clean the projector frequently to prevent dust from settling on the surface. A dirty lens may ruin the quality of the projected image.

• The main unit is very hot immediately after turning off the projector. Wait until the projector cools down sufficiently (more than 1 hour) before cleaning the projector. Otherwise, you may get burned or injured.
• Before cleaning the projector, be sure to remove the power plug from the AC outlet. Otherwise, electric shock or fire may result.

Wipe the projector's main unit softly with a soft cloth. If the projector is heavily soiled, soak the cloth in water with a small amount of detergent in it, squeeze the cloth very well, and then wipe the projector with it. After cleaning, wipe the projector with a dry cloth.

• Never use volatile cleaning liquid or benzene, as these may damage the finish of the projector.
• When using a chemical dust cloth, make sure to read the instructions thoroughly.
• When cleaning the projector's lens, use a commonly available air blower or lens cleaning paper. The lens surface is easily damaged, so do not use a hard cloth or tissues.

When Not Used for an Extended Period of Time Be sure to attach the lens cap on the lens and store in the supplied carrying bag.

Cleaning and Replacing the Air Filter

An air filter is installed in the air intake vent on the bottom of the main body to protect the lens and mirror from dust. Should the air filter become clogged with dust, the projector may be damaged since it will block the air flow into the projector and raises the temperature of the projector.

• The main unit is very hot immediately after turning off the projector. Wait until the projector cools down sufficiently (more than 1 hour) before cleaning the projector. Otherwise, you may get burned or injured.
• Before cleaning or replacing the air filter, be sure to remove the power plug from the AC outlet. Otherwise, electric shock or fire may result.
• Do not insert any object into the projector through the air filter opening. You may suffer electric shock or injury due to the high-voltage parts or rotating parts.

Cleaning the Air Filter

Turn the projector upside down, remove the cover by pushing the latch, remove the air filter, and clean it with a vacuum cleaner.

• Clean the air filter frequently.

Replacing the Air Filter 1 Turn off the projector, disconnect the power plug from the AC outlet, and let the projector stand for at least 1 hour. 2 Remove the filter cover by pushing the position of the arrow. 3 Remove the air filter. 4 Install a cleaned or new air filter. 5 Install the filter cover securely without any space.

Lamp Handling Precautions

This projector uses a high-pressure mercury lamp which must be handled carefully and correctly as mentioned below.

The mercury lamp has the following characteristics.

• A lamp may explode with a loud sound or burn out due to a shock, scratch, or use beyond its expiry date.
• The lamp life may differ from lamp to lamp and according to the usage environment. There is no guarantee that all lamps will last for the same period of time. Some lamps may fail in a shorter period of time than other similar lamps.
• A lamp gradually becomes darker over time.

If the projector indicates that the lamp should be replaced (i.e., the LAMP REPLACE indicator lights up twice),

• The chances of an explosion increase. Replace the lamp with a new one immediately if such is the case.

If a Lamp Explodes

• If a lamp explodes, gas or dust may come out of the exhaust vent. Open windows and doors for ventilation.
• The gas contains toxic mercury. Always keep your face away from the exhaust vent when the projector is operating to avoid inhaling mercury vapors or to prevent it from getting in your eyes or mouth.
• If you inhale the gas or the shards of the broken lamp contact your eyes or mouth, consult a doctor immediately.
• If a lamp explodes, its shards may scatter inside the projector. Ask the Canon service representative to clean and check the inside of the projector and replace the lamp.
